There are approximately four days a year in Britain where you can feasibly get away with drinking several frozen pina coladas without risking immediate hypothermia. And on one of those days, you should absolutely be going to Bar Elba. A huge rooftop bar in Waterloo, this place is a strictly boozy affair that really comes into its own when the weather is glorious, thanks to the jugs of sangria, massive group tables, and summer-ready colourful aesthetic. When it comes to food you can expect your classic stomach-liners like hot dogs, loaded fries, and BBQ chicken wings, but really you’re here for the drinks. FYI they also host regular outdoor cinema nights.
